An articulated surgical instrument for enhancing the performance of minimally invasive surgical procedures is coupled to a positioning mechanism for supporting and moving the surgical instrument. The positioning mechanism mounts to an operating room table. The instrument has a high degree of dexterity, low friction, low inertia and good force reflection and the positioning mechanism provides a large range of motion to the instrument. The system is operated according to a macro-micro actuation scheme which allows for a large range of motion of the surgical end effector and also allows for sensitive force feedback to a master controller by reducing the measured inertia of the slave system. The macro-micro actuation scheme may be used in conjunction with impedance scaling and force scaling between the instrument and the master controller.

[ What is claimed is:] [1.] A system for minimally invasive surgery comprising an articulated surgical instrument, a positioning mechanism and a controller wherein:the articulated surgical instrument is adapted to be inserted into a patient through a small incision to a location adjacent a surgical worksite and comprises a surgical end effector connected by a wrist mechanism to an elongate support member which is coupled to a mounting bracket wherein the mounting bracket is adapted to releasably connect the surgical instrument to the positioning mechanism and wherein the surgical instrument is operated by four actuators to move the end effector of the surgical instrument with four degrees-of-freedom relative to the mounting bracket;the positioning mechanism comprises a base which is fixed relative to the patient, a support bracket adapted to releasably connect to the mounting bracket of the surgical instrument, and an arm linkage connecting the base to the support bracket wherein the arm linkage comprises a plurality of rigid links and joints and is operated by two actuators to move the support bracket with two degrees-of-freedom relative to the base whereby the combination of the positioning mechanism and the surgical instrument is operative to move the end effector of the surgical instrument with six degrees-of-freedom relative to the base;wherein the surgical instrument provides force feedback to the controller in at least three degrees-of-freedom; and wherein the positioning mechanism provides no force feedback to the controller.
